Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a faucet. Background Technology

[0002] Faucets are commonly used household water flow control switches. To achieve aesthetic appeal, a split-type faucet structure has emerged on the market, allowing for multiple color options. For example, Chinese Patent Publication No. CN214789550U discloses an anti-loosening connection structure for a split-type faucet, including a faucet body, an outer connector, and an inner connector. The faucet body has a body connection end, and the outer connector has an outer connector connection end. The outer connector connection end and the body connection end are sealed together and connected. An anti-rotation limiting structure is provided between the outer connector connection end and the body connection end to prevent the outer connector from rotating relative to the faucet body. One end of the inner connector is screwed to the body connection end, and the other end forms an anti-loosening limiting fit with the outer connector to securely lock the outer connector at the body connection end. Although the faucet meets the color matching requirements, the faucet body and the external connector are sealed with an O-ring. If the installation angle between the faucet body and the external connector is not correct during assembly, or if the external connector is tightened too quickly, the O-ring may deform or fall off, ultimately leading to the risk of faucet leakage and affecting user experience.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0028] Reference Figures 1 to 4As shown, a faucet includes a faucet body 1, an outer connector 2, and an inner connector 3. The faucet body 1 has a body connection end 10, and the outer connector 2 has an outer connector connection end 20. The outer connector connection end 20 is connected to the body connection end 10 and forms a communication. An anti-rotation limiting structure is provided between the outer connector connection end 20 and the body connection end 10 to prevent the outer connector 2 from rotating relative to the faucet body 1. The body connection end 10 has a sealing gasket 4. One end of the inner connector 3 is screwed to the body connection end 10 and abuts against the sealing gasket 4, so that the inner connector 3 and the body connection end... 10. A sealed connection is formed, with the other end of the inner connector 3 mating with one end of the outer connector 2 to securely lock the outer connector 2 at the body connection end 10. A sealing ring 5 is provided between the inner connector 3 and the outer connector 2. Since a sealing gasket 4 is provided inside the body connection end, and one end of the inner connector 3 is screwed to the body connection end and abuts against the sealing gasket, the inner connector is sealed to the faucet body. Compared with the O-ring seal in the prior art, it has the advantages of being less prone to deformation and falling off, and being more securely installed. This ensures that the faucet is not prone to leakage. Moreover, the sealing gasket is thicker than the O-ring seal, and has a longer durability.

[0029] Specifically, a through hole 40 is formed in the center of the sealing gasket 4, which communicates with the inner connector 3, so that water from the external pipe enters from the outer connector 2 and communicates with the faucet body.

[0030] In addition, a sealing groove 30 for fixing the sealing ring 5 is provided on the outer wall of the inner connector 3. The sealing groove 30 is arranged circumferentially along the outer wall of the inner connector 3.

[0031] To prevent axial rotation of the external connector 2 relative to the faucet body 1 when connecting the external connector to the wall pipe, this embodiment uses a hexagonal anti-rotation limiting structure. However, other structures can also be used, such as triangular or square anti-rotation limiting structures. The key is to prevent axial rotation of the external connector 2 relative to the faucet body 1. It is understood that those skilled in the art can design specific structures according to their specific needs.

[0032] In this embodiment, the preferred anti-rotation limiting structure is a hexagonal anti-rotation limiting structure, wherein the hexagonal anti-rotation limiting structure includes an inner hexagonal structure 11 formed inside the body connecting end 10 and an outer hexagonal structure 21 formed at the end of the outer connector 2 connecting end, and the outer hexagonal structure of the outer connector connecting end is adapted to the inner hexagonal structure of the body connecting end.

[0033] In addition, a threaded section 22 is provided on the outer connector 2 at the end away from the external hexagonal structure, and a limiting protrusion ring 23 is provided on the external hexagonal structure 21 and the threaded section. A stepped limiting part 24 is formed inside the outer connector 2. The stepped limiting part 24 can be used to fix the outer connector 2 and the faucet body 1 to the inner connector 3.

[0034] It should be noted that the inner connection end 10 of the main body is formed with internal threads 12 that are screwed into the inner connector 3. The sealing gasket 4 is provided at the bottom of the internal threads. One end of the inner connector 3 is formed with a threaded connection part 31 that is connected to the internal threads 12, and the other end is formed with an anti-loosening flange part 32. The inner connector 3 is fitted inside the outer connector 2, and the threaded connection part 31 of the inner connector 3 is screwed together with the internal threads 12. The anti-loosening flange part 32 is tightly pressed against the step limiting part 24 to form an anti-loosening limiting fit.

[0035] It should also be noted that the inner connector 3 has a locking hole 33 formed therein, which facilitates locking the inner connector 3 to the main body connection end 10. The locking hole 33 is an internal hexagonal locking hole structure formed inside the inner connector. However, those skilled in the art should understand that in other embodiments, the locking hole 33 of the inner connector 3 can also be other types of locking hole structures, and is not limited to the internal hexagonal locking hole structure disclosed in this embodiment. For example, it can also be an internal pentagonal structure, etc., as long as it can conveniently lock the inner connector 3 to the main body connection end 10. Those skilled in the art can choose according to specific needs.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
